/etc/vsftpd.conf配置文件详解

# Example config file /etc/vsftpd.conf
#
# The default compiled in settings are very paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
#
# Allow anonymous FTP?
anonymous_enable=YES ’是否允许anonymous登录ftp服务器，默认是允许
#
# Uncomment this to allow local users to log in.
local_enable=YES’是否允许本地用户登录ftp服务器，默认是允许，不包含id为500以下用户
#
# Uncomment this to enable any form of FTP write command.
write_enable=YES ‘是否允许用户具有在ftp服务器文件中具有写的权限，默认是允许
#
# Default umask for local users is 077. You may wish to change this to 022,
# if your users expect that (022 is used by most other ftpd’s)
local_umask=022 ’设置本地用户的文件生成掩码022
#
# Uncomment this to allow the anonymous FTP user to upload files. This only
# has an effect if the above global write enable is activated. Also, you will
# obviously need to create a directory writable by the FTP user.
#anon_upload_enable=YES ‘是否允许匿名用户上传文件
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
#anon_mkdir_write_enable=YES ’是否允许匿名用户在ftp中创建目录
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory.
dirmessage_enable=YES ‘激活目录信息，当远程用户更改目录时，将出现提示信息
#
# Activate logging of uploads/downloads.
xferlog_enable=YES   ’启用上传和下载日志功能
#
# Make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=YES ‘启用ftp数据端口的连接请求
#
# If you want, you can arrange for uploaded anonymous files to be owned by
# a different user. Note! Using “root” for uploaded files is not
# recommended!
#chown_uploads=YES
#chown_username=whoever
#
# You may override where the log file goes if you like. The default is shown
# below.
#xferlog_file=/var/log/vsftpd.log ’设置日志文件的文件名和路径
#
# If you want, you can have your log file in standard ftpd xferlog format
xferlog_std_format=YES ‘是否使用标准的ftpd xferlog日志文件格式
#
# You may change the default value for timing out an idle session.
#idle_session_timeout=600  ’设置空闲的用户会话中断时间，单位是秒
#
# You may change the default value for timing out a data connection.
#data_connection_timeout=120 ‘设置数据连接超时时间，默认是120秒
#
# It is recommended that you define on your system a unique user which the
# ftp server can use as a totally isolated and unprivileged user.
#nopriv_user=ftpsecure
#
# Enable this and the server will recognise asynchronous ABOR requests. Not
# recommended for security (the code is non-trivial). Not enabling it,
# however, may confuse older FTP clients.
#async_abor_enable=YES
#
# By default the server will pretend to allow ASCII mode but in fact ignore
# the request. Turn on the below options to have the server actually do ASCII
# mangling on files when in ASCII mode.
# Beware that turning on ascii_download_enable enables malicious remote parties
# to consume your I/O resources, by issuing the command “SIZE /big/file” in
# ASCII mode.
# These ASCII options are split into upload and download because you may wish
# to enable ASCII uploads (to prevent uploaded scripts etc. from breaking),
# without the DoS risk of SIZE and ASCII downloads. ASCII mangling should be
# on the client anyway..
#ascii_upload_enable=YES
#ascii_download_enable=YES 是否允许使用ASCII格式来上传和下载文件
#
# You may fully customise the login banner string:
#ftpd_banner=Welcome to blah FTP service. ’在ftp服务器中设置欢迎登陆信息。
#
# You may specify a file of disallowed anonymous e-mail addresses. Apparently
# useful for combatting certain DoS attacks.
#deny_email_enable=YES
# (default follows)
#banned_email_file=/etc/vsftpd.banned_emails
#
# You may specify an explicit list of local users to chroot() to their home
# directory. If chroot_local_user is YES, then this list becomes a list of
# users to NOT chroot().
#chroot_list_enable=YES
# (default follows)
#chroot_list_file=/etc/vsftpd.chroot_list ‘如果希望用户登录后不能切换到自己目录以外的其他目录，需要设置该项，如果设置chroot_list_enable=yes,那么只允许/etc/vsftpd。chroot_list中列出的用户具有该功能。如果希望所有的本地用户都执行chroot，可以增加一行：chroot_list_user=YES
#
# You may activate the “-R” option to the builtin ls. This is disabled by
# default to avoid remote users being able to cause excessive I/O on large
# sites. However, some broken FTP clients such as “ncftp” and “mirror” assume
# the presence of the “-R” option, so there is a strong case for enabling it.
#ls_recurse_enable=YES ‘允许用ls -R命令
pam_service_name=vsftpd’设置pam认证服务的配置文件名称，该文件存放在/etc/pam.d/目录
userlist_enable=YES ‘用户列表中的用户是否允许登陆ftp服务器，默认是不允许
#enable for standalone mode
listen=YES ’使vsftpd处于独立启动模式
tcp_wrappers=YES ‘使用tcp_wrappers作为主机访问控制方式
max_clients=100 ‘设置同时连接服务器的并发用户为100
max_per_ip=2 ‘设置每用户同一时间段并发下载线程数为2，同时只能下载2个文件
anon_max_rate=20000 ‘设置匿名用户的最大传输速率为20kbps
local_max_rate=1000000设置本地用户的最大传输速率为1MBPS
